PATENT OFFICE ROWLAND SPENCER, OF ST. ANNES-ON-SEA, ENGLAND MULTIPLE-FLY WOVEN FABRIC Application led May 10, 1928. Serial No. 276,743, and in Great Britain .Tune 27, 1927.

The present invention relates to an improved multiple ply woven fabric.

The present invention is particularly suitable for use as a covering for drying cylinders of paper making machines, since it is possible thus to produce a material having a coated surface and a cotton internal structure. That is, the material has both the absorptive property of the worsted in its presentation against the wet sheet, and also they resistance of the worsted animal fibre with respect to the acid which is usually present in the paper web. The vegetable fibre such as cotton employed on the interior, however, is of much greater tensile strength and is much less expensive than worsted, although less absorptive, and less adapted to yield off its moisture rapidly.

According to the present invention a textile fabric is formed of multiple ply construction composed partly of doubled cotton yarns and partly of cotton and worsted yarns doubled together.

The invention is more particularly described with reference to the accompanying drawing showing in section one preferred arrangement of multiple ply cloth.

The diagram shows a four ply cloth formed of weft 1, 2, 3, 4, of doubled worsted and cotton. Each line of warp as will be noticed, binds the weft of two adjacent lines. The warp threads 5, 6, 7, of the three lower plies are of doubled cotton, Whilst the warp 8 of the upper ply is of 4doubled worsted and cotton. This outer ply will therefore, form the surface layer and will form a fabric particularly suitable as a cover for the drying cylinders of paper making machines.

Instead of making the wefts 2, 3, 4, of doubled worsted and cotton, these or certain of them may be either simply cotton and worsted or cotton.

I declare that what I claim is A multiple ply cloth adapted to form a cover for the drying cylinder of a papermaking machine composed of weft of doubled cotton and worsted, the outer ply having a Warp of doubled cotton and worsted, the warps of other plies being of doubled cotton.

In witness whereof, I have hereunto signed my name this 26th day of April, 1928.
